Make this easy Graham Cracker Toffee, often called Christmas Crack, at home. This recipe delivers a shatteringly crisp, buttery toffee layer over graham crackers, topped with rich chocolate. It is superior to store-bought versions and perfect for holiday gifts.

Ingredients

Scale
  • 1 sleeve graham crackers (about 13 full sheets)
  • 1 ¼ cups unsalted butter
  • 1 ¼ cups packed dark brown sugar
  • 1 teaspoon vanilla extract
  • 12 ounces semi-sweet chocolate chips
  • Optional: ½ cup chopped pecans or sea salt for topping

Instructions

  1. Preheat your oven to 350°F (175°C). Line a large baking sheet with parchment paper or aluminum foil and arrange the graham cracker sheets in a single layer to cover the bottom completely.
  2. In a medium saucepan, combine the butter and brown sugar. Bring the mixture to a boil over medium heat, stirring constantly. Boil for exactly one minute, then remove from the heat immediately.
  3. Stir the vanilla extract into the hot toffee mixture.
  4. Pour the hot toffee evenly over the graham crackers, spreading quickly to cover all the crackers.
  5. Bake for 5 minutes. The toffee should be melted and bubbly.
  6. Remove the pan from the oven. Immediately sprinkle the chocolate chips evenly over the hot toffee layer. Let the chocolate sit for 5 minutes to soften.
  7. Spread the softened chocolate into an even layer. If using, sprinkle chopped nuts or sea salt over the chocolate now.
  8. Let the toffee cool completely at room temperature, or place it in the refrigerator for about 30 minutes until the chocolate is firm.
  9. Once set, break the toffee into irregular pieces. Store in an airtight container.

Notes

  • For a salty-sweet flavor, sprinkle flaky sea salt over the melted chocolate right after you spread it.
  • You can substitute semi-sweet chocolate chips with milk chocolate or white chocolate chips for variation.
  • If you want a nut-free version, skip the pecans or use sprinkles instead.
